I use nextcloud news for rss feeds, and ground news for regular summaries and breaking news, as if I’m important enough to need to know everything right away.
When I heard about the Y2K panic in the mid 90s the very first thing I did (as a kid) was advance my clock to 12/31/1999 to see what would happen next.
IIRC when the date changed, it went back to some date in the 1980s I think. This was either windows 95 or 98, I can’t remember.
Anyway that advice to turn your computer off… What the heck? Then what, throw it away?
I don’t remember much about how to use kubernetes but if you can specify a tag like nextcloud:28 instead of nextcloud:latest you should have a safer time with upgrades. Then make sure you always upgrade all the way before moving to a newer major version, this is crucial.
